Bronsons - Borderlands 3 Farming Guides
Location: The Blastplains on Gehenna
Part of: Crew Challenge (Bounty of Blood DLC)
Drops: Brightside (Tediore Shotgun)
The Bronsons are one of the available Crew Challenges on the planet Gehenna which is part of the Bounty of Blood DLC for Borderlands 3. You'll find these guys at the northern most portion of the map in The Blastplains, shown in my screenshot above.
As far as loot goes you should expect to find a Brightside (Tediore Shotgun) here. This gun is not unique to The Bronsons and can drop off of any other enemy throughout the Bounty of Blood DLC as well.
